Specification forming part of Letters Patent No. 76,920, dated April 2l, 1868.

improved gate,A Fig. 2, a transverse sectional elevation of the same.

"*This invention relates to that class ot'gates which are arranged s0 that equestrians and those riding in carriages may open and shut themlwithout alighting; and its nalure'consiste iu a gate hung on friction-rollers arranged to run on opposite sides of a concaveconvex track having sharp or thin edges conforming to the peripheries of the rollers, and a ovel device -for supporting the pulleys over hich the cords for running the gate are made gto pass.

To enable others skilled in the art to fully.

comprehend the construction and operation of my invention, I have marked corresponding parts with similar lettersfand will now give a detail description.

-A represents the ground, which is made to' support a double post, C C, through which the gate.. is made to run; two posts, B B, for the supportcf the cords It in a convenient position to be reached from a carriage; a tracksupport, E, and a jan1b-.post, D,- all-ot' which `are' arranged similar to other gates of this class, except the double post C C, which is vmade to iform a part of the box for pulleys S T, as `seen at Figs. l and 2, and support the track J K. This track has a novel construction, and as follows: The cheapest plan is to use a piece of hard-wood plank, and out the surplus edges away, so as to make `long curves \K K and a short curve, d, hetweemas seen at 1, and then cover the 'ed-ges on which the rollers .M L run with strap or cast irouformed to suit grooves in the peripheriesef said rollers.

latter being used `to support straps V V, rig-Av idly-'attached to said' posts, and having holes made through them,"in which the pivots-'of rollers M L revolve. vThe double post G C is made to form-a partof the box W, which supports the -rollers T S, the latter being set parallel. with gateF andthe former transversely with it, and the cord-s R R, attached tothe 'gate lpulleys N Njand extend down-toa'conveuient position in the usual manner. y y By this means a cheap,- ccnvenent, and substantialgate is provided, and one whichcan pable of pulling-down fifteen or twenty vpounds order by snow and ice, as the sharp edges oit the track will always cut its way clear on the rollers. It isunderstood `that either of the cordsltwillopen and shut the gate, itbeing ing passed through.

Having thus described myihvention, what I claim, and

is 1. The concavoconvex trackxJ ,arranged for combination with straps V and gate-F, sub-- stautially as and for thepurpose set forth.`

2'.' The .com'bi'uationof track J', cords It', strapsV, pulleys stantially asset forth.
